Your kingdom does not lie in things themselves, but in the meaning that things have? Your ideas?

I think that the term "your kingdom" might mean (at least to me it does) that what you think of things are not real in themselves but only in what we THINK they are. Like when someone swears that Christ was not a Muslim or even Hindu when in reality he spoke the same truths as Mohammad and Krishna spoke of. It is all the same to me....
